Hi David,

Not all meteorites respond to a magnet. You very well could have a lunar, or one of the other classifications that have little if any metal in their petrology. You'll need to have it cut and a sample examined by an expert. Your "meteor wrong" just might be a rarer example of a "meteor right".
